SLC6A2 encodes the sodium-dependent noradrenaline transporter NAT1 which terminates the action of the neurotransmitter noradrenaline by transporting it from the synapse back to its vesicles for storage and reuse (Broer & Gether 2012, Schweikhard & Ziegler 2012). SLC6A2 is expressed in the CNS and adrenal glands. Defects in SLC6A2 can cause orthostatic intolerance (OI; MIM:604715), a syndrome characterised by lightheadedness, fatigue and development of symptoms during upright standing, relieved by sitting back down again. Plasma norepinephrine concentration is abnormally high (Lambert & Lambert 2014).
